## Long description

Extralink SUR190-s is an OTDR fiber fault locator that operates at 1310 nm and 1550 nm wavelengths, designed for testing single-mode fiber links. The device detects breaks, splices and connectors, measures event locations and loss, and provides distance information to faults. Its portable form factor and targeted wavelength range make it suitable for installation, maintenance and troubleshooting tasks in telecom and data network fibers.
Advantages
The SUR190-s provides clear identification of reflections and attenuation along single-mode fibers at both 1310 nm and 1550 nm, enabling precise fault localization. The instrument’s portability and simple operation allow technicians to perform on-site tests quickly. Measured distance and loss values assist in evaluating link quality and documenting repair needs. The dual-wavelength functionality supports common field diagnostics for long-haul and access fibers.
Suitable for
Locating breaks and macrobends in single-mode fiber links
Verifying splice and connector loss during installation
Troubleshooting signal attenuation on telecom and data network fibers
Maintenance checks and periodic fiber link verification
Key specifications
Operating wavelengths: 1310 nm and 1550 nm for single-mode fiber testing
Functions: fault location, event detection, distance measurement and loss measurement
Portable, handheld form factor for field use
Suitable for installation, maintenance and troubleshooting workflows
How to use
Connect the SUR190-s to the fiber under test using the appropriate interface and ensure proper connector cleanliness before testing. Select the desired test wavelength (1310 nm or 1550 nm) according to fiber type and the distance range to inspect. Initiate a scan to generate an OTDR trace that shows events, reflections and attenuation points; read distance and loss information from the trace output. Interpret the trace to locate breaks, high-loss splices or faulty connectors and record measurements for documentation.
Usage recommendations
For reliable results, clean connectors before each measurement, allow the instrument to stabilise after powering on, and choose the wavelength that best matches the fiber span and expected fault characteristics. Use the device in combination with visual inspection tools and power meters when full link verification is required.
